RuntimeInitializeOnLoadMethod

The documentation is not correct about this function running after awake. It does by default, but not if you specify a load type:

The order of callbacks is: ¹⁾

SubsystemRegistration
AfterAssembliesLoad
BeforeSplashScreen²⁾
BeforeSceneLoad
Unity MonoBehaviour.Awake() runs here
AfterSceneLoad, Default

Providing no load type defaults to RuntimeInitializeLoadType.AfterSceneLoad, running the function after Awake.

Other versions that have been verified to also use this exact order:

2021.1.12f1 (editor only)

Methods with RuntimeInitializeLoadType.AfterSceneLoad, or RuntimeInitializeLoadType.BeforeSceneLoad will only be called for the first scene in a run of the application, not every scene. Tested on Unity 2019.4.19f1, Other LoadTypes are untested but would be presumed to be the same.

¹⁾

tested in the editor, 2020.2.1f1 and 2020.1.17f1. Also tested in editor and in build in 2019.4.12f1

²⁾

On 2019, this call didn't seem to run in the editor, I think this was fixed with the addition of the previous two load types.
